As water Rarified doth make Winds blow,
So winds when Rarified do Colder grow;
For if they much be Rarified , then they
Do further Blow , and spread out every way;
So Cold they are as they like Needles prick;
Through thinness they do break, and cannot stick,
But into Atomes fall, whose Figures be
Sharp , and peirce porous Bodies , as we see.
Yet some will think, if Air were parted so,
The winds could not have such strong force to blow:
True, Atomes could not peirce, if they were found
To be all Dull, Flat, Heavy, Blunt or Round ;
But by Dividing they so Sharp do grow,
That through all porous Bodies they do go;
But when the Winds are soft, they intermix
As Water doth, and in one Body fix;
They rather wave than blow, as Fans are spread,
Which Ladies use to cool their Cheeks when red:
Or like as Water drops , that disunite,
Feel harder, than when mixt they on us light,
Unless such Streams upon our heads do run,
As we a shelter seek, the Wet to shun;
But when a Drop congealed is with Cold ,
As Hail-stones are, then it more strength doth hold;
For Flakes of Snow may have more quantity
Than Hail-stones , yet they've no such force thereby;
They fall so Soft that they scarce strike our touch ,
Hail-stones we feel and know their weight too much.
But Figures that are Flat are dull and slow ,
Make weak Impressions wheresoe're they go;
For let ten times the quantity of Steel
Be beaten small, no hurt by that you'l feel;
But if that one will take a Needle small,
Whose point is sharp , and prick the Flesh withall,
Strait it shall hurt, and put the Flesh to pain,
Which greater strength doth not of what is plain ;
For though you press it hard against the Skin ,
'T may heavy feel, but cannot enter in:
And so the Wind that's thin and rarifi'd
May press us down, but never peirce the side.
Or take a Blade that's Flat , though strong and great,
And with great strength upon ones Head it beat,
You'l break the Skul , but not knock out his Brains;
Which Arrows sharp soon do, and with less pains.
This what is small, is subt'ler and more quick;
For all small Points in porous Bodies stick.
Winds broken small to Atomes , when they blow,
Are Colder much than when they streaming flow:
For all that's joyned and united close,
Is stronger much, and gives the harder Blows .
This shews what's closest in it self to be,
Although an Atome in its small degree;
Take Quantity for Quantity alike,
And Union more than Mixture hard shall strike.
